Publication Metadata only The Effects of Perioperative Factors on Early Postoperative Morbidity in Bariatric Surgery(2022) ORHON ERGÜN, MELİHA; Zengin, Seniyye Ulgen; Orhon Ergun, Meliha; Gunal, OmerPublication Metadata only Goal-Directed Fluid Management Using Plethysmographic Variability Index in Patients Undergoing Laparoscopic Bariatric Surgery(MARY ANN LIEBERT, INC) ORHON ERGÜN, MELİHA; Ergun, Meliha Orhon; Zengin, Seniyye Ulgen; Umuroglu, TumayBackground: Optimal intraoperative fluid management is essential in surgical patients, including individuals with obesity undergoing bariatric surgery. The objective of this study was to assess the feasibility of pleth variability index (PVI) for intraoperative goal-directed fluid management in comparison with standard approach, in patients with obesity undergoing laparoscopic bariatric surgery. Methods: A total of 60 patients with obesity who underwent elective laparoscopic bariatric surgery were included in this single-blind prospective randomized study. Patients were randomly assigned to the PVI group or control. Patients were monitored for PVI, heart rate, noninvasive mean blood pressure, and perfusion index. In addition, administered fluids, amount of bleeding, and renal function parameters were recorded. Results: The PVI group received higher amounts of crystalloids (3053 +/- 275 mL vs. 1703 +/- 349 mL, p < 0.001) and colloids (277 +/- 208 mL vs. 17 +/- 91 mL, p < 0.001) intraoperatively, and it had higher perioperative urine output. In addition, the PVI group had decreases in blood urinary nitrogen (BUN), lactate, and creatinine levels; however, controls had increased BUN, lactate, and creatinine. Conclusions: Findings of this study suggest that PVI may represent a useful noninvasive strategy for intraoperative goal-directed fluid management in patients with obesity undergoing laparoscopic bariatric surgery.Publication Metadata only Neutrophil gelatinase associated lipocalin in predicting postoperative acute kidney injury in elderly(SPRINGER LONDON LTD) ORHON ERGÜN, MELİHA; Orhon Ergun, Meliha; Zengin, Seniyye Ulgen; Mustafayeva, Aynur; Umuroglu, TumayBackground Elderly patients are at increased risk of developing acute kidney injury (AKI) following major surgery and rapid diagnosis is essential. Aim This study aimed to examine the potential utility of plasma neutrophil gelatinase associated lipocalin levels in early prediction of AKI in geriatric patients undergoing laparotomic oncological surgery. Methods This prospective single-center cohort study included 60 geriatric patients (>= 65 years of age) that underwent major oncologic surgery with laparotomy. Perioperative measurements of plasma creatinine, blood urinary nitrogen, plasma lactate, urine output, and neutrophil gelatinase associated lipocalin (NGAL) were made. Patients were followed for AKI development, which is the primary outcome measure, and predictive role of NGAL was investigated. Results At 48 h follow-up, AKI developed in 13 patients (21.7%). Significant differences in creatinine (p < 0.001), NGAL (p < 0.001), and urine output levels (p = 0.001) were evident over time between the two groups. High NGAL measurements at 6 and 24 h after surgery seem to be highly predictive of AKI development. At 6 h, a plasma NGAL level greater than 71.8 ng/mL has a sensitivity and specificity of 85% and 81% in predicting subsequent AKI development. Conclusions Plasma NGAL levels seem to represent an early and reliable marker for AKI in elderly patients undergoing laparotomic surgery with the potential to allow early diagnosis and prevent further renal deterioration. Further confirmatory studies are warranted. Trial registration The study was registered to ClinicalTrials.gov (number, NCT05030727). Implication statement Elderly patients are at increased risk of postoperative acute kidney injury (AKI). This study shows that plasma neutrophil gelatinase associated lipocalin is a helpful marker to predict AKI in elderly patients undergoing laparotomic major surgery, which will allow early diagnosis and prevent further renal deterioration in this vulnerable patient group.Publication Metadata only Pediatrik torakotomi vakasında erektor spina plan bloğu deneyimimiz(2022-10-25) ORHON ERGÜN, MELİHA; ZENGİN, SENİYYE ÜLGEN; ORHON ERGÜN M., GÜÇLÜ E., ZENGİN S. Ü.Publication Metadata only The outcomes of using high oxygen concentration in pediatric patients(SPRINGER HEIDELBERG) HARMAN, FERHAT; Saracoglu, Ayten; Zengin, Seniyye Ulgen; Ozturk, Nilufer; Niftaliyev, Seymur; Harman, Ferhat; Aykac, ZuhalOxygen reserve index, available as part of Masimo Rainbow SET pulse oximetry, is a noninvasive and continuous variable intended to provide insight into a patient's oxygen status in the moderate hyperoxic range (PaO2 > 100 and <= 200 mm Hg), defined as a patient's oxygen reserve. When used in conjunction with pulse oximetry, ORi extends the knowledge on a patient's oxygen status providing clinically important information helping to prevent hyperoxemia and hypoxemia. There are limited data on patients undergoing craniosynostosis surgery. Our primary goal was to evaluate the effects of different concentrations of inspiratory oxygen (FiO(2)) on patient oxygenation status by monitoring ORi. Thirty patients scheduled for craniosynostosis were included in this observational cohort study. Patients were randomized into two equal groups: Group 1 received a fraction of inspired oxygen of 0.8 and group 2 received a FiO(2) of 0.6 during induction of anaesthesia. In addition to standard haemodynamic variables with ORi were recorded at baseline 1 min, 5 min, 60 min, and 120 min after intubation. Postoperative complications, length of stay in the intensive care unit and hospital were recorded. In total, 14 patients were evaluated in each group. Gender, age, BMI, ASA scores were similar between groups (p > 0.05). In Group 1, ORi values were significantly higher when compared to group 2 at baseline (0.86 +/- 0.21 vs 0.45 +/- 0.32, p = 0.001), one minute (0.61 +/- 0.24 vs 0.27 +/- 0.21, p = 0.001), and 5 min (0.34 +/- 0.31 vs 0.10 +/- 0.13, p = 0.033). High inspired oxygen concentration during induction of anesthesia in pediatric patients is associated with higher levels of ORi. Therefore, ORi may provide the means to safely reduce the inspired oxygen fraction during inhalational induction in paediatric patients.Publication Metadata only Effect of Ultrasound-Guided Erector Spinae Plane Block on Postoperative Pain and Intraoperative Opioid Consumption in Bariatric Surgery(SPRINGER, 2021) ORHON ERGÜN, MELİHA; Zengin, Seniyye Ulgen; Ergun, Meliha Orhon; Gunal, OmerBackground Bariatric surgery is often associated with moderate to severe pain. In patients with obesity, opioids have the potential to induce ventilatory impairment; thus, opioid use needs to be limited. This study aimed to compare the novel ultrasound-guided erector spinae plane block (ESPB) technique with controls in terms of intraoperative opioid consumption and postoperative pain control. Methods A total of 63 patients with morbid obesity who underwent laparoscopic bariatric surgery were included in this randomized study. Patients were randomly assigned to the bilateral erector spinae plane block (ESPB) group or the control group. To evaluate perioperative pain and to adjust opioid dose, analgesia nociception index (ANI) was monitored during surgery. Total opioid dose was recorded for each patient. In addition, pain was evaluated using visual analogue scale (VAS) scores for 24 h following the operation. Results Total intraoperative remifentanil dose was significantly lower in the ESPB group when compared to controls (1356.3 +/- 177.8 vs. 3273.3 +/- 961.9 mcg, p < 0.001). In the ESPB group, none of the patients required additional analgesia during follow-up. In contrast, all control patients required analgesia. ESPB group had significantly lower VAS scores at all postoperative time points (p < 0.001 for all). Conclusion Bilateral ultrasound-guided ESPB appears to be a simple and effective technique to improve perioperative pain control and reduce intraoperative opioid need in patients with morbid obesity undergoing bariatric surgery.Publication Metadata only Traumatic Avulsion of Upper Eyelid Skin Following Surgery in a Patient With Multiple Myeloma and Amyloid Light-chain Amyloidosis(HMP, 2020) ZENGİN, SENİYYE ÜLGEN; Ergun, Selma Sonmez; Zengin, Seniyye Ulgen; Unal, Mustafa; Yildiz, PelinMultiple myeloma (MM) is a common hematologic malignancy. Primary systemic amyloidosis or amyloid light-chain (AL) amyloidosis is a rare disease. PURPOSE: This article presents the case of a patient with MM and AL amyloidosis who experienced a severe case of medical adhesive-related skin injury. CASE STUDY: A 64-year-old man with MM, AL amyloidosis, and diabetes presented with a necrotic wound on his left heel that required surgical debridement. The patient experienced a traumatic avulsion of the right upper eyelid skin during the removal of the corneal abrasion preventive tape as well as traumatic avulsion of the left upper eyelid skin while the patient's face was being cleansed. The avulsed right upper eyelid skin above the tarsus was repaired with a full-thickness skin graft. The partly avulsed left upper eyelid skin was repositioned, and an excisional biopsy was taken. Both upper eyelids healed uneventfully. The biopsy specimen revealed increased amyloid deposition in the dermis, subcutaneous tissue, and areas surrounding the veins and sweat glands. CONCLUSION: This case illustrates the increased risk of medical adhesive-related skin injury and other skin damage in patients with MM and AL amyloidosis. In these patients, the use of tape should be avoided to prevent intraoperative corneal abrasion.Publication Metadata only İnternal juguler ven kateterizasyonun subaraknoid penetrasyonu ve komplikasyon yönetimi(Akademisyen Kitabevi, 2023-01-01) ORHON ERGÜN, MELİHA; ZENGİN, SENİYYE ÜLGEN; ORHON ERGÜN M., ZENGİN S.
